Ruby - Join an Array into a String

1. Introduction

Often in programming, there is a need to convert an array of strings or values into a single concatenated string. Ruby, with its rich set of built-in methods, provides the join method to achieve this task seamlessly. In this post, we'll explore how to use Ruby's join method to combine an array of words into a string.

2. Program Steps

1. Set up the Ruby development environment.

2. Create an array of words or strings.

3. Use the join method to combine the array into a single string.

4. Display the joined string to the user.

3. Code Program

# Create an array of words
words_array = ["Ruby", "is", "an", "amazing", "language"]
# Use the join method to combine the array into a single string
joined_string = words_array.join(" ")
# Display the joined string to the user
puts "Joined String:"
puts joined_string

Output:

Joined String:
Ruby is an amazing language

Explanation:

1. words_array: This is an array containing individual words that we aim to join.

2. join: The join method is utilized to concatenate elements of an array into a single string. By providing a space (" ") as the delimiter, the words are joined with spaces between them.

3. puts: This method is used to display output to the console.

With Ruby's join method, converting an array of elements into a cohesive string becomes a straightforward task.
